Dometic MasterFlush 7640 Discontinued? Meet the All-New MF410 (Now in Bone)

If you've been searching for a Dometic MasterFlush 7640, here's what you need to know: the 7640 has been discontinued. Its replacement is the all-new Dometic MasterFlush MF410, and the bone color is finally available to order.

The MF410 is the new 7640. It's a pedal-flush macerating RV toilet, and it's the only one on the market today. If you loved your 7640 because it flushes with a foot pedal like a regular RV toilet, but can sit anywhere in your rig, the MF410 is the toilet you're looking for.

What happened to the MasterFlush 7640?

Dometic has ended production of the MasterFlush 7640 (part numbers 304764001 white and 304764002 bone). The MF410 is Dometic's new pedal-operated macerating toilet in the MasterFlush line, built to take the 7640's place.

Already own a 7640? Parts for existing 7640 toilets are still available, so you can keep yours running. When it's time for a new toilet, the MF410 is the one to replace it with.

What makes the MF410 different

• Pedal flush. Flush with your foot, just like a standard RV toilet. No buttons, no switches.
• Macerating pump. Waste is ground up and pumped to your holding tank, so the toilet doesn't have to sit directly over the tank.
• Redesigned bowl. A new, more space-saving bowl shape.
• Fewer tank odors. Because the toilet isn't mounted right on top of the waste tank, tank odors stay out of the bathroom.

That flexibility makes the MF410 a great fit for a second bathroom in a motorhome, fifth wheel or travel trailer, or anywhere a gravity toilet just won't work.

Will the MF410 fit where my 7640 was?

The MF410 is the 7640's successor, but it has a different bowl. Before you order, compare the MF410's footprint, rough-in and mounting dimensions against your 7640 and your bathroom layout.

Not sure? Contact us with your 7640 model number and a few measurements, and we'll help you confirm the fit.

MF410 vs. Dometic 410: don't mix them up

The names are close, but these are very different toilets. The Dometic 410 is a gravity-flush toilet in the 400 Series. The MasterFlush MF410 is a pedal-operated macerating toilet. Look for the "MF" in the model name before you order.
